The Rippers can be killed with two Power Bombs, or one carefully placed Power Bomb and a careful dodge of the top-most Ripper. With a single Power Bomb, place it at least two tiles above the first Ripper. This can be achieved with a Staggered IBJ or a Spring Ball Bomb Boost. Then climb the right side of the shaft and dodge the top Ripper.
